ADAM HERIG, OFCLEVELAND, OHIO.

HEAT-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent N 0. 720,346, dated February 10, 1903.

Application filed May 20, 1902. Serial No. 108,286. (No model.)

To all whom it may concern.-

Be it known that I, ADAM HERIG, a citizen of the United States of America, and a resident of Cleveland, county of Ouyahoga, and State of Ohio, have invented certain new and useful Improvements in Heat-Distributers, of which the following is a specification.

This invention relates to heat-distributors for hot-air furnaces; and it consists of additional improvements on my Patent No. 687,154, dated November19, 1901. These improvements have for their object to provide for making the distributor adjustable, so as to make it capable of adjustment to fit different-sized register-boxes, thus avoiding the necessity of making several sizes of distributers for the little variations in the sizes of registers.

This improvement consists in making separate corner-pieces and side and end plates for the distributer-boxes and joining said parts together with bolts inserted through slots to enable them to be easily and exactly increased or diminished in length and width to adapt them to the register-box.

In the accompanying drawings, Figure 1 is a perspective view of my improved distributer-box. Fig. 2 is a vertical section on line 2 2 on Fig. 1. Fig. 3 is a detached view of one of the corner-pieces. Fig. 4 is a similar view of a corner-piece with extended sides.

D D are corner-pieces that may be made of one piece of metal out and bent to form the outside and inside walls (1 d. The inside walls, which form the hot-air fiue, and which is somewhat smaller than the outside casing, have a portion cut away at the middle and have the out edges brought together and joined to make the inside corner-seam d of the said inside air-flue and the downward corner extensions (1 These extensions are provided to be inserted in the inside edges of the register-boxes for retaining them in place. This construction provides the open space between the outside walls of the box and the walls of the hot-air flue.

E E are perforations in the lower parts of the outer walls for the admission of the cold air from the floor, and the chamber within the inside walls forms the flue for the passage of hot air from the furnace.

F G represent, respectively, the side and end plates of the distributer-box, which are formed with two walls in like manner to the corner-pieces. They are provided with slots 6 c, and when their side edges are inserted in the corner-pieces are secured in place by bolts 9 9 through the corner-pieces and the said slots, the obvious purpose and object of which is that the said corner-pieces and the side and end plates may be adjusted for increasing or diminishing the width and length of the box for closely fitting the floor registerboxes B, which frequently differ in size.

Fig. 4 represents a corner-piece of greater width than D D, which may be joined together with a lap at the middle of the sides and ends of the box and fastened by bolts in slots in like manner to the corner-pieces D to the side plates F G. This method may be employed in making small-sized boxes.

Having now described my invention, what I claim is The heat-distributer consisting of the corner-pieces D D, comprising an inner and an outer wall and provided with the projections
